Collection Method: clinical testing

The c.352G>A (p.G118S) alteration is located in exon 5 (coding exon 4) of the FAXDC2 gene. This alteration results from a G to A substitution at nucleotide position 352, causing the glycine (G) at amino acid position 118 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
